CLOSURE-OPERATOR.

Specification of Letters Patent. Patented 0V. 9, 1920.

Application filed January 23, 1920. Serial No. 353,514.

To all whom it may concern:

Be it known that I, LEONARD M. PHELPS, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Closure-Operator, of which the following is a specification.

This invention relates to improved closure operators, and more particularly to devices especially adapted for operating slidable closures, such as window sashes or bin doors.

The primary object of the invention is. to provide means for simultaneously moving a plurality of window sashes to their closed positions upon the closing of a predetermined sash or master sash, thus making it possible to instantly close all of the windows of a building in case of tire, or rain.

A further object of the invention is to provide'mechanical means for moving the sashes to their respective closed positions, which means being especially adapted to cushion the downward movement of the sashes to eliminate any jar caused by the sash contacting with the window sill.

ivith the foregoing and other objects in view which will appear as the description proceeds,rthe invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing Figure 1 illustrates the operating means as applied to a number of windows, one of the side walls of one of the frames being shown as broken away to illustrate the 1118- chanical operating means;

Fig. 2 illustrates a sectional view through the latch mechanism employed on the various windows to be operated;

Fig. 3 illustrates a sectional view taken on line 3-8 of Fig. 2; and

Fig. 1 illustrates a sectional view through the controlling lever.

Referring to the drawings intdetail, the device is shown as including a main or master sash 5, and a sash 6, representing a sash .to be operated or controlled by the movement of the master sash 5.

The sash 5 is provided with a bracket 7 supported by the upper rail of the lower section. of the sash, which bracket is provided with a flange 8 adapted to contact with the controlling arm 9, which lies in the path of travel of the flange 8, in its down ward movement.

This controlling arm 9 is secured to one of the side walls of the frame in which the sash is operating by means of the bracket member 11. The arm 9 has pivotal connection with the bracket member 11, through the pivot pin 12, and the lug 13, carried by the bracket member 11 extends outwardly from the bracket and contacts with the upper edge of the arm 9 to restrict the upward movement of the arm 9, thus insuring the arm being normally supported in a horizontal position, or in a position. to be properly engaged by the flange 8.

Forming a part of the controlling arm 9 is an extension 14 pivotally connected to the arm 9, there being a lug 15 provided on the arm 9 and extending laterally therefrom for contacting with the underside of the extension 14 to prevent the extension 1 ifrom moving out of horizontal alinement with the edges of the arm'9, when the same is engaged by the flange 8 of the bracket 7.

From the foregoing it is of course obvious that when the sash 5 is moved to its upper, or open position, the upper surface of the flange 8 will contact with the extension 14, and cause thesame to pivot upwardly, which will in no way affect the remaining elements of the operating mechanism.

It might also be found desirable to move the extension 14: to the position as indicated in dotted lines in Fig. 1 of the drawings, thus throwing the extension out of operative relation, or out of the path of travel of the, flange 8, thus permitting the sash 5 to be moved to its open or closed position.

Extending from the inner side wall of the frame 15, is a bracket 16 which is preferably formed of sheet metal, having the bosses 17 and 18 formed thereon, the edges of which bosses lie in the same plane and hold the pivoted arm 19 under'tension in a PI'EClQtQI'". mined position.

The arm 19 is supported by the spring bracket 20, which is secured to the bracket 16 as at 21, the arm 19 also having pivotal connection with the bracket 20, through the bolt 22 passing through suitable registering openings in the arm 19 and bracket 20. The lower end of the arm 20 is hooked as at 20 to engage under the lower edge ofthe lower sash when the same is in its open or raised position.

The frame for the sash 6 is preferably hollow, as at 23 to provide a housing for the coiled spring 24L which has its upper end connected to the bracket 25, which in turn is secured to one of the side rails of the sash 6 and extends within the housing, the opposite end of said coiled spring 24 having connection with the flexible member 25 which supports the weight 26, on one end thereof, there being a guide 27 secured within the housing for guiding the flexible member 25, which operates through the guide 27.

It will thus be seen that when the sash 5 is in its raised position, the spring 24 is under tension, and that when the arm 20 is moved to release the sash 6, the coiled spring 2e urges the sash 6 downwardly to its closed position. a

The length of the flexible member 25 is such that the lower end or weighted end thereof, moves to a point adjacent the window sill before the sash closes, thus permitting the sash to close under its own momentum Connecting the arms 9 and 19, is a flexible member 28 which operates over the pulleys 29 and 30 of the window frames, so that movement of one arm, or more particularly arm 9 results in a relative movement of the arm 19.

In the operation of the device, assuming that the windows are in positions as indicated by Fig. 1 of the drawings, the sash 5 is moved to a closed position, whereupon the flange 8 of the bracket 7 contacts with the extension 14:, in its downward movement, moving the arm 9 to a position as indicated in dotted lines in Fig. 1.

It follows that the arm 19 is moved upwardly causing the same to be disconnected from the bosses 17 and 18, with the result that the coiled spring, and-weight 26 cause the sash 6 to move to its closed position.

' While I have shown and described the invention as applied to a pair of window forming a part of a locking means for normally locking the closures in a predetermined position, means carried by the master closure for contacting with the pivoted lever, for causing a movement of the pivoted lever, and means for connecting the pivoted lever and arms whereby movement of the lever causes .a relative movement of the arms.

2. A closure operator including in combination, a plurality of closures including a master closure, pivoted arms carried by the closures, means cooperating with the pivoted arms for supporting the closures normally in a predetermined position, resilient means having connection with the respective closures for moving the closures in one direction, a pivoted lever supported adjacent the master closure, means for connecting the pivoted lever and pivoted arms, means carried by the master closure for contacting with the pivoted lever for causing a movement of the pivoted lever, and flexible means connecting the pivoted arms and lever, whereby movement of the pivoted lever causes a relative movement of the pivoted arms to release the closures.

3. A closure operator including in combination, a plurality of closures including a master closure, means for connecting the closures, means controlled by the master closure for releasing the remaining closures, means for applying pressure to the closures for moving the closures to a closed position, and means for relieving the closures of said pressure before the closures reach their closed position to eliminate noise or jar.

4:. A closure operator comprising in combination,a masterclosure and a plurality of auxiliary closures, the auxiliary closures having frames, said frames being hollow to provide housings, spring members supported in the housings and having connection with the frames, latch members for normally holding the auxiliary frames in an open position, apivoted lever supported adjacent the master closure, and having connection with the latch members, and means carried by the master closure and contacting with the pivoted lever for moving the pivoted lever for causing a relative movement of the latch members.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
